Abstract (en)

[origin: WO9607794A1] A process for heating an asphalt surface and an apparatus therefor. The process comprises the steps of: igniting in a burner (30) a combustible mixture comprised of a fuel (50) and oxygen (60) to produce a hot gas; and feeding the hot gas to an enclosure having a radiative face (200) disposed above the asphalt surface (280). The asphalt surface heating apparatus comprises a hot gas producing burner (30) and an enclosure (25) comprising an inlet (120) for receiving hot gas from the burner and a radiative face (200) having a plurality of apertures. The apertures in the radiative face are of a dimension such that the hot gas: (i) heats the radiative face to provide radiation heat transfer to the asphalt surface; and (ii) passes through the apertures to provide convection heat transfer to the asphalt surface.
